Re: The Second Restated and Amended Loan and Security Agreement between Jaco
and Nexus, as Debtor and The Bank of New York Commercial Corporation, as
Lender, and each other Lender a party thereto, dated September 13, 1995, as
amended and supplemented (the "Loan Agreement")

Ladies/Gentlemen:

In connection with the above referenced Loan Agreement, you have requested: (a)
a prospective reduction in the Contract Rate (with all initially capitalized
terms not defined herein, but which are defined in the Loan Agreement, to have
the meaning therein set forth) applicable to LIBO Rate Loans first arising
after the date hereof; and (b) the consent of the Lenders in order to permit a
repurchase by Debtor of up to $3,000,000 in their capital stock.

The purpose of this letter is to set forth our mutual understanding in respect
of such matters as of the date hereof as follows:

(a) Subdivision (A) of the definition of "Contract Rate" in the Loan Agreement
(which immediately precedes the word "or" appearing therein) is hereby amended
to read as follows:

"(A) in the case of LIBO Rate Loans first arising, or first continued or
converted thereto on or after 4/10/96, (i) the applicable LIBO Rate plus (ii)
two percent (2%), and, in the case of LIBO Rate Loans first arising, or first
continued or converted thereto before 4/10/96, (i) the applicable LIBO Rate
plus (ii) two and one-half percent (2-1/2%);"

(b) Each of the Lenders also hereby consents to the repurchase by Debtor of up
to $3,000,000 in their capital stock, provided however that: (i) immediately
following any such repurchase and to the extent that after giving effect
thereto, the maximum amount that would then otherwise be permitted pursuant to
the terms and conditions of Paragraph 4 (a) of the Loan Agreement

   2
would exceed the outstanding balance of all Loans, inclusive of the Term Loans
and all Letters of Credit, by an amount of not less than ten million dollars
($10,000,000); and (ii) any such repurchase occurs before the third anniversary
of the Closing Date at the very latest; and

(c) Furthermore, each of the undersigned additionally hereby confirm that: (i)
as of May 1, 1996, a merger of Fleet Bank of New York, N.A. into NatWest Bank
N.A. is to occur, with the resulting bank title of such merged institution
being Fleet Bank, N.A., (ii) by reason of the merger and name change and as of
May 1, 1996, any and all references to NatWest Bank N.A. in the Loan Agreement
shall be replaced by references to Fleet Bank, N.A. f/k/a NatWest Bank N.A.
instead, and (iii) accordingly, as of May 1, 1996, the Loan Agreement shall be
amended, in order to reflect all of the matters described in this paragraph and
the identification of Fleet Bank, N.A. as a "Lender" and as a "Secured Party"
thereunder, with a corresponding amendment to be simultaneously made to all
related agreements, instruments and documentation.

Except to the extent herein specifically set forth, no change to the Loan
Agreement is intended or implied and the Loan Agreement, modified as set forth
above is hereby ratified and confirmed in all respects. If the foregoing is in
accordance with your understanding, would you kindly sign below to so indicate.

                                     Very truly yours,

                                     THE BANK OF NEW YORK COMMERCIAL CORPORATION
